Scattering of x rays by the bound and free electrons in dense plasma

We present a method for calculating the total x-ray-scattering cross section as a function of angle for kilo-electron-volt x rays scattered by partially ionized hot dense plasma. The calculational procedure is based on determining the separate contributions of bound and free electrons to the scattering cross sections. Basic distributions needed for the calculation are obtained by solving the Thomas-Fermi model in the correlation sphere, where both electrons and ions are accounted for. The results indicate significant changes in the intensity and angular distribution of the scattering cross sections between different plasma conditions and between plasma and cold material.
